WATER-MOTOR.

BPECIFICATION forming part of Letters Patent No. 395,530, dated January1, 1889.

Application filed August 3, 1888. Serial No. 281,872. (No model.)

T 0 all whom it may concern.-

Be it known that I, HENRY E. TRUMBLE, a citizen of the United States,residing at Kalamazoo, county of Kalamazoo, State of Michigan, haveinvented a new and useful ater- Motor, of which the following is aspecification.

This invention relates to a motor disclosed in another pendingapplication of mine, filed March 27, 1888, Serial No. 268,668, in whicha piston appears like the one herein shown, composed of two platesjointedly attached together end to end, and arranged in a (inme orwatercourse, as below described.

The object of the present invention is to devise improvements in thestops which control and limit the movement of the free end of thepiston, for the purpose which will appear farther on.

A further object is to provide the eduction of the fiume orexhaust-ports with automatic valves, so as to hold the water in theflume on one side of the piston while the piston moves in one direction,and to let the water thus held exhaust before the piston moves in theother direction.

In the drawings forming a part of this specification, Figure l is a planwith the top wall of the flume removedthat is, if the flume laid in ahorizontal position it would be a plan view, but if used in a verticalposition it would be an elevation; Fig. 2, a broken part of one side ofthe flume and one of the stop-gates in Fig. 1, in enlarged perspective;and Fig. is a broken part of the pivoted end of the piston and theexhaust-valves in Fig. 1, in enlarged perspective.

Referring to the letters marked on the drawings, B is a water-flume. Forconvenience, and from the fact that the motor is more especiallydesigned for water, I use the term water, but any elementsueh as steam,air,

vapor, &c.which will operate the piston may" be employed. The pistoncomposed of )arts A and l), the same being bars or plates, are jointedor hinged together end to end,'Fig. 1. This piston is placed in theflume 13, one end being pivoted therein by a pivot, S. The other end isleft free to play between the stopgates. These gates c c are hinged atone end to the walls of the flunie at 2', Figs.

stop-gates 'c prevent the water from flowing between the wall of theflume and the end of the piston which rests against the stop-gate. (Seeupper right hand in Fig. 1.) Of course if the stops 0 were dispensedwith and the end of the piston rested against the wall of the flume, thewater could not flow behind it; but it is frequently desirable that thestops should be adjustable.

The piston-rod a is attaclwd to the pistons at the joint, as describedin the above-named. prior application, but claimed in thisapplication,because the drawings clearly illustrate the motor employingthis style piston-rod. The piston-rod extends through bearings 77..

Vhile the piston will work in the water flowing through the flumewithout any valves or gates in the eduction-ports, still greater poweris secured by partially closing said ports at the time, as explained inthe operation below.

A successful valve is shown in Figs. 1 and 3. It consists of the obliquewings r r, attached to the ends of a cross-piece, which is centrallypivoted in the flu me by the pivot S, which pivots the end of thepiston; but it may have a separate pivot, if preferred. In most cases itis desirable that the wings 7' be of a size to not entirely stop theflow of water, so that the free end of the piston will more promptlytilt from one stop 0 to the other.

In Fig. 1 the water is supposed to be exhausting from the right-handside of the flume and flowing into the left-hand side, as the free endof the piston rests against the right-hand stop-gate c, preventing thewater from flowin into this side. The water flowing through theleft-hand side has tilted the valves, as in Fig. 1, closing the port atthe left and opening the right-hand port. The pressure of the wateragainst the left side of the piston forces it over to the right side ofthe fiuine, and as soon as this action has taken place the water tiltsthe free end of the piston over against the left-hand stop-gate lettingthe water in at the right side of. the piston, which water tilts thevalve the other way, closing the right-hand port and opening theleft-han d port. Thus the operation continues.

The valves are limited in their movement by coming in contact with theWalls of the fl'ume or some suitable stop. In Fig. 1 the walls of thefluine are hollowed out at e e, forming shoulders for the ends of thevalves to contact with, and thus limit their movement.

My design is to employ a fiume having a piston of this style formeasuring liquids and fluids, thus utilizing it for a meter as well as amotor.

Having thus described m y invei it-ion, what I claim, and desire tosecure by Letters Patent, 1s'

' 1. The combination of a suitable tlnme having induction and ednetionports, automatic exhaust-valves in the lattmr-named ports, and thejointed piston, substantially as set forth.

2. The combination of a suitable fiume, the jointed piston pivotedtherein at one end, and the adjustable stop-gates consisting of thewings hinged in position for the free end of the piston to contact withand the screws for adjusting the wings, substantially as set forth.

The combination of a suitable fiume, an automatioallvoscillating pistontherein in the plane of the flowing water in the fiuine, and theadjustable stop-gates for the free end of the piston to contact with,consisting of the wings hinged in the induction-port, and means forswinging the wings in or out, substantially as set forth.

In testimony of the foregoing I have hereunto subscribed my name inpresence of two witnesses.
